Etymology. The specific epithet is a noun in apposition from the department of the type locality of the species.

Diagnosis. Males of Tenedos huila sp. n. resembles those of T. valle sp. n. by having large basal tegular membrane (BTM) ( Figs 38A–D ; 39A–B ), but can be distinguished by retrolateral tibial apophysis with wider posterior branch (pRTA) provides of a small protuberance, and wider, apically bifid anterior branch (aRTA); apically thinner, rounded without tips or projections median apophysis (MA) ( Figs 34 , 35A–D ; 36A–B ). Females are similar to those of Tenedos valle sp. n. by the shaped of atrium (A) and copulatory ducts ( Figs 38E–F ; 39C–D ), are characterized by the smaller copulatory ducts (CD) and median field plate (MFP) rounded in the base ( Figs 34E–F ; 35C–D ).

Female (Paratype, IAvH-I-6168). Coloration and abdominal pattern of spots as male with some modifications: carapace uniformly brown, legs light brown, abdominal spots more rounded ( Fig. 33C–D ).
